PREFACE TO THE SECOND EDITION. 



* I ^HIS work has been so favorably received in all parts of the 

 English-speaking world, that it is with a special satisfaction 

 that the author responds to the demand for a second edition. 

 In the new edition he avails of the opportunity to carefully re- 

 -vise the first, so as to bring it in line with the latest advances in 

 veterinary medicine. To accomplish this over one hundred and 

 fifty pages have been added to the first volume, embracing the 

 more important achievements made since the first edition was 

 published, and the author bespeaks for the new issue, a contin- 

 uance of that appreciation which has been so liberally accorded 



to the first.
